Pouch batteries are increasingly used due to good safety and high energy density. Typically, pouch batteries include a series of lithium ion pouch batteries disposed in a closed protective housing. However, in some cases, such as when a lithium ion battery is overcharged or aged, the pouch cell may swell. Thus, the closed housing will be subjected to increased pressure from the inside, which results in a potential safety hazard. A technical solution is needed to solve or at least alleviate the above technical problems.

Detailed Description
Embodiments of the present invention will be specifically described below. It is to be understood that the embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.
According to the present invention, there is provided a secondary battery including; a housing 1, the housing 1 having an interior cavity; a lithium ion pouch battery 2, the lithium ion pouch battery 2 including an electrical connection terminal 4 exposed to the outside of the case 1; the secondary battery further includes a gas discharge mechanism 5 formed of a compressible material and formed in the form of a balloon to discharge the pressure generated in the internal cavity to the outside of the case 1 by the discharge of the balloon of the compressible material, and the lithium ion pouch battery pack 2 and the compressible material are both located in the internal cavity of the case 1 and sealed in the encapsulating layer 3.
It is to be understood that the secondary battery of the present invention may be used not only for electric vehicles but also extended to any lithium ion secondary battery packaging application, such as portable electronic devices or stationary battery backup devices.
In practice, the lithium-ion pouch battery 2 may comprise at least one lithium-ion pouch battery comprising an external seal and a liquid or slurry electrode material encapsulated by the seal. More generally, however, as shown in fig. 2, the lithium ion pouch battery pack 2 may include a plurality of pouch battery cells. The technical scheme of the invention is widely applied to the design of the package of any type of lithium ion soft package batteries.
The case 1 provides the secondary battery with an integral structure and appearance, has an inner cavity for mounting the encapsulation layer 3, and the airbag is sealed in the encapsulation layer 3. The compressive material may be used to contain or absorb the expansion space of the lithium ion pouch battery 2. Although the casing 1 is shown as a rectangular parallelepiped as a whole in the drawings, the present invention is not limited thereto, but is applicable to casings of other shapes. The electric connection terminal 4 is connected to the lithium ion pouch battery pack 2 and exposed to the outside of the case 1 through the encapsulation layer 3 and the case 1.
As described above, the main difference from the conventional technical solution is that in the technical solution of the present invention, a vent mechanism 5 is provided, and the vent mechanism 5 releases the internal pressure generated in the internal cavity to the outside of the housing 1 through the venting of the air bag of the compressible material, so that when the lithium ion pouch battery pack 2 is expanded in use, the pressure in the internal cavity can be released, for example, in such a manner that the air in the internal cavity is allowed to flow into the external environment in a controllable manner, thereby achieving the object of the present invention.
The air release mechanism 5 may have various forms as long as it is based on the release of the internal pressure generated in the internal cavity to the outside of the housing 1 by the air release of the air bag of the compressible material. According to one embodiment of the invention, the venting means 5 comprise at least one passage connecting the inner space of the airbag and the outside of the housing 1 and in this way the inner space of the airbag communicates directly with the outside of the housing 1 through the passage. For example, at least one through hole is provided through the case 1 and the encapsulating layer 3. The communication of the inner space of the airbag with the outside of the housing 1 is achieved by at least one passage passing through the through-hole and connected to the inner space of the airbag so that the gas in the inner space of the airbag can be discharged to the outside. The through hole can be arranged at a proper position of the shell 1 so as not to influence the installation of the lithium ion soft package battery pack 2 on the basis of realizing the invention. And the number and the geometric parameters of the through holes can be selected and designed according to different working conditions.
As clearly shown in fig. 2 and 4, according to an embodiment of the present invention, the air discharge mechanism 5 includes at least one air discharge passage made of a compressible material, interposed between the lithium ion pouch battery pack 2 and the encapsulating layer 3, and communicating to the outside of the case 1. Specifically, the exhaust passage extends from the inside of the airbag to the outside of the housing 1 to release the internal pressure generated in the internal cavity to the outside of the housing 1.
Specifically, the exhaust passage includes a plurality of outer ends 51, and the plurality of outer ends 51 protrude from different outer surfaces of the housing 1, respectively. For example, in the embodiment shown in fig. 4, the outer ends 51 protrude from two opposite surfaces of the housing 1, respectively, although other surfaces may be selected as needed. However, it should be understood that the invention is not limited to these and the vent passage may take other forms, for example, the outer end 51 of the vent passage may be coplanar with the outer surface of the housing 1 or more inwardly directed than the outer surface of the housing 1.
The part of the exhaust channel located inside the housing 1 can be realized by different designs. In one embodiment, the exhaust passage includes at least one main passage 52 and a plurality of branch passages 53, the main passage 52 is connected to the outside of the housing 1, and the branch passages 53 are in fluid communication with the main passage 52. In particular, said main channel 52 can be connected to the outside of the casing 1 by an outer end 51 projecting from the main channel 52, and in this case, successively through the branch channel 53, the main channel 52 and the outer end 51, a communication is achieved between the inside of the airbag and the outside of the casing 1 to discharge the gas inside the airbag to the outside, and finally, the pressure generated inside in said inner cavity is released.
Preferably, as shown in fig. 2, the exhaust passage includes two main passages 52 parallel to each other and a plurality of branch passages 53 disposed in parallel between the two main passages 52 and connected to the two main passages 52. In the embodiment of fig. 2, the exhaust passage includes two outer ends 51, two main passages 52, and a plurality of branch passages 53. Each of the outer ends 51 is connected to a first side (a side toward the outside of the battery) of the main channel 52 of the corresponding side at the center of the main channel 52, a plurality of branch channels 53 are parallel, and both ends of each branch channel 53 are respectively connected to a second side (the second side is opposite to the first side) of the main channel 52 of the corresponding side at the center of the main channel 52 one by one along the main channel 52, so that different regions in the inner space of the airbag are communicated with the main channel 52, and then the outer ends 51 are communicated to the outside. However, the present invention is not limited to the above, but the shape and characteristics of the exhaust mechanism 5 may be designed differently according to different operating conditions, for example, the exhaust mechanism 5 may include an arc-shaped channel or a serpentine-shaped channel, or one channel assembled by connecting different channels, and the main channel 52 and the branch channel 53 may be connected in other shapes.
More preferably, as shown in fig. 2, 3 and 5, each lithium ion pouch battery includes a battery body having a battery tab 21, a plurality of lithium ion pouch batteries are disposed adjacent to each other, the corresponding battery tabs 21 are electrically connected and a plurality of spacing spaces are formed between the battery tabs 21, and the branch passages 53 are respectively located in the corresponding spacing spaces. The corresponding battery tabs 21 of adjacent pouch cells are electrically connected in series or in parallel. Also, some of the battery tabs 21 are spaced apart from each other to form a spacing space. Preferably, in order to achieve a compact spatial layout for increasing the energy density, the branch channels 53 are therefore each located in a respective spacing space, as shown in fig. 5.
Preferably, as shown in fig. 5, when the secondary battery is used, the vent mechanism 5 is located at the top of the lithium ion pouch battery pack 2, and the battery tab 21 is generally located at the top side.
As described above, the inner cavity of the housing 1 can directly communicate with the outside through the exhaust mechanism 5. However, in a preferred embodiment, the inner cavity of the housing 1 communicates indirectly with the outside, for example, the venting means 5 comprises at least one-way valve located at the outer end 51 of the venting channel and allowing the air pressure inside the air bag to be released to the outside of the housing 1. The one-way valve prevents air flow from entering the inner cavity of the housing 1 to avoid influencing the influence of the outside on the inner cavity of the housing 1 and simultaneously avoid foreign objects from entering the inner cavity of the housing 1.
Also, preferably, when the check valve is closed, the air pressure inside the air bag is higher than the pressure outside the case 1, which means that the threshold air pressure at which the check valve opens unidirectionally is higher than the atmospheric pressure to establish communication of the internal cavity of the case 1 with the outside when the air pressure inside the air bag is higher than the pressure outside the case 1, and thereby the air discharge of the air bag by the compressive material even releases the internal pressure generated in the internal cavity to the outside of the case 1 to ensure the safe working environment of the secondary battery to some extent and avoid potential danger.
And the compressive material used to form the bladder may be disposed immediately adjacent to one or more of the lithium ion pouch cells.
